hijacked browsers/denied permission for programs

Recently my laptop got hit with a virus that hijacks all browsers, taking them to ad pages. Also when I try running programs like MBytes,HJT, and Spybot I get a message saying "cannot locate path, device. you may not have permission". I tried in safe mode, same issue. I also ran Mbytes and Spybot off of usb flash drive but after a few seconds of scanning, they close.(unable to run HJT from usb). Any help would be appreciated.

Hello, Use this fix, when you see a box that states “Windows cannot not access the specified device, path, or file. You may have inappropriate permissions to access the item”.

Download This FileSave it next to mbam.exe (this file is located in the Malwarebytes Anti-malware home folder). Once done, drag and drop mbam.exe into Inherit.exe. Click OK and attempt to run Malwarebytes Anti-malware once again.

Post the MBAM logThe log is automatically saved and can be viewed by clicking the Logs tab in MBAM.Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.

DO NOT post an HJT log here if needed we will ask for it.

I added the file. I still got the pop up when trying to load from desktop (mbytes icon is white) but was able to load from start up menu. unfortunately Mbytes closed as soon as I clicked scan. Also my firewall popped up asking to allow/block. I tried the one on usb, same thing. closes once scan begins

If you cannot use the Internet,you will need access to another computer that has a connection.From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program. If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.

I may lose power here as I am in the path of Irene.

I reinstalled, added file from above. it ran. as soon as scan started, MBAM closed. that seems the biggest issue, is getting it to scan with out closing. Also, while I was on, I noticed a new process with a whole bunch of numbers. it's exe and can't be killed. and np, I can leave laptop off.

This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!Be sure to downloadTDSSKiller.exe(v2.5.9.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.

Double-click on TDSSKiller.exe to run the tool for known TDSS variants.Vista/Windows 7 users right-click and select Run As Administrator.

If TDSSKiller does not run, try renaming it.

To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer toHow to change the file extension.

Click the Start Scan button.

Do not use the computer during the scan

If the scan completes with nothing found, click Close to exit.

If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.

Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.

A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).

Copy and paste the contents of that file in your next reply.

If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to these[/color] instructions. [color=green]In some cases it may be necessary to redownload TDSSKiller and randomly rename it before downloading and saving to the computer.

Now try MBAM again.

I ran TDSSKiller and 3 issues popped up. 1 allowed me to cure the other 2 wouldn't. I instead changed their options to delete upon reboot. After reboot, the issue that was able to set to cure was gone but the other two still remain. This time the one issue, Rootkit.Win32.ZAccess.c gave the option, which I set it to cure, rebooted. Ran scan again and still there. The other issue, is hidden. I'll include a screen shot.

Ok, Reboot and rerun . Cure the Access and skip the other and post the log. Try MBAm again after that.

I clicked cure, and skipped the hidden. Rebooted and it is still there. MBAM still closes after it begins to scan. I've tried it a third time, and same issue. For some reason, TDSSKill isn't curing it.

nope, MBAM still closes as soon as the scan begins. I ran it from my USB cause for some reason, even after using the inherit.exe file in the MBAM folder, after the laptop resets, MBAM no longer is accessible, its icons turn white on desktop. Also, if this helps the Rootkit.Win32.ZAccess.c and hidden file that showed up in TDSSkiller are still on the computer.
